Title: High-temp. galvanising process - with removal of excess iron@ from the molten zinc@ by means of a zinc removal and cooling stage
Inventor: SCHUSTER KLAUS
IPC: C23C2/06
Filed: 1991-01-15
Abstract: In a process for the high-temp. galvanising of articles made of iron or iron alloys, molten Zn is maintained at a temp. above 530 deg.C, pref. at 560 to 640 deg.C, and is not saturated with iron. Pref., the supersaturated iron is crystallised out from the molten Zn from time to time as an Fe/Zn phase by reducing the temp. of the molten Zn. This crystalline phase is then removed from the Zn. Part of the molten Zn is continuously or intermittently fed from the galvanising bath into a separate vessel, and a corresp. amt. is fed from the vessel back to the galvanising bath. The temp. in the vessel is maintained at a lower temp., partic. 530 deg.C. The molten Zn removed is cooled in a heat exchanger by means of the molten Zn fed back into the galvanising bath. USE/ADVANTAGE - Used to protect iron articles from corrosion by providing a relatively thin Zn layer which cannot be obtd. by other galvanising processes.

Patent DE-4122599-A1 (DE)
Inventor: BREITLING FRANK
IPC: C12R1/19
Filed: 1991-07-08
Abstract: A phagemide has been constructed that expresses an antibody merged to coliphage pIII protein.

Patent DE-4136706-A1 (DE)
Inventor: ROHLEDER SABINE DIPL ING
IPC: B29C59/04
Filed: 1991-11-07
Abstract: A temperature-controllable roller 1 serves as a sealing tool, on the circumferential surface of which a plurality of plastics film webs 14, 15, 16 are sealed to one another under pressure and the application of heat. The plastics film webs run onto the circumferential surface of the roller 1 at equal or different distances from one another and are guided by means of pressure rollers 2, 3, ... 7. These pressure rollers lie under pressure against the circumferential surface of the roller 1. The plastics film webs pass through the contact areas between the pressure rollers and the roller 1. The plastics film webs are covered on one or both sides with sealing layers which are fused by the effect of heat so that a sealing of the laminated plastics film webs occurs on the circumferential surface of the roller 1. Between at least two superposed plastics film webs, no sealing layers are present so that the laminate can be separated into individual laminates at the sealing layer-free surfaces along a partial circumference of a separating roller (30). <IMAGE>
